Lets's calculate LCM of 646,789
Given numbers has no common factors except 1. So, there LCM is their product i.e 509694
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/509694
Therefore, the GCF of Fractions 699/646,636/789 is 3/509694
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 646,789 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(646,789) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(646,789) x common factors =1 x 1 = 1
LCM(646,789) = ( 646 × 789 ) / 1
LCM(646,789) = 509694 / 1
LCM(646,789) = 509694
